Anyone know Fungi? Got it in my head (since the Devonian period thing I mentioned) that Barnacles and UAs are like fungi and their spores. So thought ramble on the "Baby Barnacle" theory.
Check out a nifty picture

The pegs are sterigmata, the big grey thing is called a basidium. Bigger more educational picture is here:

Which if you stick the Basidium underground and have a big protrusion in the middle you get something that looks like a barnacle site. What's above ground is the Sterigmata spikes and growing on those are the UA looking spore things. I wish we could do a proper excavation on barnacles and see if there'd be a proper underground network of weird.
MB hinted at an origin "I'm afraid not - the nebula that they can be found in relates to their origin and I can't talk about that." So there is an origin to this stuff, but what bugs me is the shell. Call out to this awesome site made by Entim :
http://entim.no-ip.org/ed/uarepository/shell . If Barnacles and UAs act like fungi and spores there should be a continuous spread of them. But there's not. The set up indicates a short moment of UA production then it stops. That is assuming UAs travel in a linear and detectable fashion. They could be instantly transmitted away from the barnacle planets, which all the barnacle planets have been in the center of the shell so far and UAs become more common in the shell over time. So have they been constantly producing them for the past half year?
In conclusion. I dunno. Could be just coincidences. There is an origin. There is a hollow sphere of UAs, and the center is peppered with barnacles. UAs sound like space whales, Barnacles look like in-organic growths, and the scientist went missing next to a black hole that formed when our planet first had spores. And all this appeared within months. Feel like I'm looking a math problem and stuck one step away from the obvious solution.
Or maybe they aren't related at all, maybe the UAs and barnacles are two opposing forces. One tries to devour everything around it, the other trying to sate the hunger. Maybe UAs started pointing to Merope, because they all detected a sudden appearance of Meta-Alloys there? It could be the Center of Mass for Barnacle locations.
